LlGHT-REFLECTING ATTACHMENT FOR TYPEeWRiTEHS- No. stacca.

Specification of Letters Patent.

Patented April, 3907 Application nea umh 20,1906. serai No'. 307.045.

Be it known that I, LEWIS J. SIMS, a citizen of the United States of Ainerica,residing at Lincoln, in the county of Logan and `State of illinois, have invented a Light-Reflecting Attachment-for 'l` vpe\Vriters, of which the following is a specification. V

This invention relates to type-writing t'n'achincs, and has reference more particularly to the provision of an attachment especiallyr adapted for use in connection with such type-writing machines as are operated 1n a dimly-lighted room. n I

The primary object of the linvention is'to provide a light-reflecting medium easily and conveniently attached to any of the typewrit-ing mac lines now in common use and so located and arranged that light from a certain direction may be reflected onto the platen-roll-of the machine in order that the printing may be more clearly seen by'the operator though the machine itself is in a dimly-lighted place.

With this principal object in view the invention consists, primarily, of a reiiecting medium-for instance, a mirror--in connection with means for attaching'| the same to a type-Writing machine and for adjusting the mirror with respect to the source of light and the laten-roll. T ie following speciiication enters Into detail description of the construction, application, and practical advantages of the invention, and what I claim as new, and desire to protect by Letters Patent of the United States, is more specifically set forth 1n the appended claim.. U I

In the accom anying drawings, which form a part hereo .Figure 1 is a front lelevation of the device. Fig. 2 is a rear elevation of the same. Fig. 3 is a longitudinal sectional View ythrough the mirror-frame and mirror carried thereby. Fig. 4 is a transverse sectional view through Fig. 3. Fig. 5 is an end elevation illustrating the application of the invention.

Like letters and numerals of reference indicate like parte in all the figures of the drawinGs.

Iln the operation of a' type-Writing `ma-. chine in a dimly-lighted room it is frequently the case that though the `operating-keys may be clearly seen by the operator yet the printed matter cannot be soweasily read, owing to the insufliciency of the light and the location ofthe platen-roll Within the machine. In l change the shape of the brackets in applying vthe device to different machines, and, in

strain his eyes to a more or less extent in an .effort to follow the printing, especially in that class of type-writing machines commonly known as .visible Writers4 it is the purpose of my invention, therefore, ,to relieve this condition by the provision of a simple and effective device which can be readily and conveniently attached to any of the ordinary type-writing machines.

In carryin" out my inventieii I .empio a rectangular lframe A., which is referalily made ofsheet metal to comprise ti e back a, end pockets a a', and bottoni ocket a2, said pockets being formed by simp y bending the ends and lower portion of the plate upon itself, as shown in Figs. 3 'and 4. This traine is adapted to hold a light-reflecting mediumfor instance, an ordinary mirror B, and so that the greater part of the face of lsaid mirror will be exposed, as illustrated in Fig. 1.

A C C designate angle-brackets by means ot which the mirror and its frame are attached to the type-writing machine., and for the purpose of supporting the mirror-frame inswing.-

ing engagement- Witli the brackets said frame is provided at each end 'centrally with a .boss b, having a threaded pin t', the latter passing through an eye in the upper end of the bracket to receive an ordinary milled thumbnut d. The thumb-nut is adapted to bind upon the bracket, so as to iirmlyhold the mirror-frame at any position to which it may be tilted or adjusted. The lower end of eacn bracket is provided with a foot-piece c, yhaving a slot c therein, by means of which the 'device may be secured u on a type-writnig machine. It will be un erstood, of course, that 1n some instances it may be necessary to act, the mirror or reilecting medium may be supported in any suitable manner. I also contemplate providing a highly-polished metal plate as a reilecting medium in place of the ordinary glass mirror, inasmuch as itis more durable and less expensive. 1'

In the application ofgthe device to a typewriting machineit is in some instances secured to thecarria e e', Fig. 5, by means of the screws which hol the usual scale-plate in place, the l'slots c in the foot-pieces of the rackets being 'provided for. this purpose.- vIn other cases it is secured to the main frame or other part of the malihine. The brackets project forwardly. and upwardly from the i from of the platen-roll -e above the center thereof and so that the mirror may be vadthree of its edges'forming shallow grooves or pockets, threaded pins projecting from the 1o ulm-in ythe mil ed thumb-nuts d.
